Violence in Afghanistan

hypothetical question for you all…..IF the soldiers sent to Iraq, i.e. 150,000 of them, were instead sent into Afghanistan and used to clean up and organize that country, would the Taliban be even heard of except when spoken about in history books?

I ask that hypothetical question because the Taliban gave full support and comfort to our enemy, Al-Qaida who attacked us on 9/11. For that, they should not even be around, yet they are.

The most powerful military on the planet cannot handle a bunch of cave dwellers?
